Interface MessagingTracingCustomizer

public interface MessagingTracingCustomizer

This allows configuration plugins to collaborate on building an instance of MessagingTracing.

For example, a customizer can setup MessagingTracing.Builder.consumerSampler(SamplerFunction) samplers} without a reference to the tracing component.

This also allows one object to customize both Tracing, via TracingCustomizer, and the messaging layer MessagingTracing, by implementing both customizer interfaces.

Integration examples

In practice, a dependency injection tool applies a collection of these instances prior to building the tracing instance. For example, an injected List<MessagingTracingCustomizer> parameter to a provider of MessagingTracing.

Here are some examples, in alphabetical order:

   
Dagger Set Multibindings
   
Guice Set Multibinder
   
Spring Autowired Collections
 

Note: This type is safe to implement as a lambda, or use as a method reference as it is effectively a FunctionalInterface. It isn't annotated as such because the project has a minimum Java language level 6.
